With the commercialization of the space sector, known as NewSpace, and thanks to the expansion of new products called small Satellites, Alter Technology, once again at the forefront of new technologies, offers a comprehensive one-stop service covering all quality assurance tests applicable to small Satellites:

  • Proper component selection
  • Performance, environmental & reliability tests
  • Custom solutions for miniaturization and de-risking
  • Full in house capabilities for small satellites validation

To create an ADDED VALUE IN small Satellites, we have two defined phases that require a series of specific tests.
